Patent CA-2180047-C (CA)
Inventor: VANDENBERG ELIS
IPC: E21B17/00

Granted: 1999-06-08
Abstract: A joint of tubular casing with a pre-formed window in its sidewall, has a tubular sleeve fixedly attached to the interior of the tubular casing by a plurality of shearable set screws. The exterior surface of the sleeve is sealed to the interior surface of the tubular casing on opposing sides of the window. The window is filled with a fluid and then the window is covered with one or more layers of a composite material such as fiberglass. In use, the joint of tubular casing is run down to the depth of interest in an earth borehole, and then the window is oriented with respect to the formation of interest at the depth. The joint of tubular casing is then cemented in place, after which the tubular sleeve is retrieved by the use of a fishing tool causing the set screws to shear upon the upward movement of the fishing tool. After the interior sleeve is retrieved, a whipstock is lowered into the cased borehole, until it is oriented and anchored therein. The assembly automatically fixes the axial and circumferential orientation of the whipstock within a surrounding casing joint and holds the assembly in place. Alignment and fixing of the whipstock ensures proper engagement and orientation of a drill bit with an access window formed in the casing wall. The assembly employs multiple spring loaded latches which register with and extend into corresponding receiving recesses formed on the inner surface of the casing joint. The recesses, which are spaced circumferentially around the interior of the casing joint, contain differing profiles which uniquely mate with corresponding profiles on the latches. The relative position of the latches with the recesses determines the amount of radial latch movement providing keyless anchoring and orientation of the assembly within the casing. Setting is positively confirmed with a simple rotational force on the setting string. The spring loaded latches release from anchored, oriented position in response to an upward axial force exerted by the drill string to provide a straight pull release of the assembly. Confirmation of correct axial location and proper circumferential orientation may be made by surface monitoring of the setting string weight and turning torque.

Abstract: A drill press has a drive motor with output shaft that drives a chuck through a rotatable and vertically displaceable quill and a first drive coupling which includes a pair of pulleys, such as cone pulleys, and a belt extended between the cone pulleys. A rotary power take-off in the form of an additional pair of pulleys and a drive belt extracts rotary power from the drive coupling between the motor and the chuck and transfers it to an oscillatory motion device. The device includes a worm and worm gear and an eccentrically mounted arm which convert rotary motion from the rotary power take-off into a reciprocating linear motion. A lever is pivotally mounted to the device with one end engaged with the quill and a remaining, opposing end coupled with the arm.      Reciprocation of the arm causes reciprocation of the lever which causes reciprocation of the quill, chuck and any tool held in the chuck. The arm is releasably engaged with and is coupled with the lever through a detent block.

Abstract: The invention provides lanthanide chelates capable of intense luminescence. The celates comprise a lanthanide chelator covalently joined to a coumarinlike or quinolone-like sensitizer. Exemplary sensitzers include 2- or 4-quinolones, 2or 4-coumarins, or derivatives thereof e.g. carbostyril 124 (7-amino-4-methyl-2-quinolone), coumarin 120 (7-amino-4-methyl-2-coumarin), coumarin 124 (7-amino-4-(trifluoromethyl)-2-coumarin), aminomethyltrimethylpsoralen, etc. The chelates form high affinity complexes with lanthanides, such as terbium or europium, through chelator groups, such as DTPA. The chelates may be coupled to a wide variety of compounds to create specific labels, probes, diagnostic and/or therapeutic reagents, etc. The chelates find particular use in resonance energy transfer between chelate-lanthanide complexes and another luminescent agent, often a fluorescent non-metal based resonance energy acceptor. The methods provide useful information about the structure, conformation, relative location and/or interactions of macromolecules.

Title: Hepatitis c virus asialoglycoproteins
Inventor: GERVASE BARBARA A
IPC: C07K14/18
Filed: 1991-11-07
Granted: 2001-08-28
Abstract: Two Hepatitis C Virus envelope proteins (E1 and E2) are expressed without sialylation. Recombinant expression of these proteins in lower eukaryotes, or in mammalian cells in which terminal glycosylation is blocked, results in recombinant proteins which are more similar to native HCV glycoproleins. When isolated by GNA lectin affinity, the E1 and E2 proteins aggregate into virus-like particles. Cells bearing a mannose receptor or asialoglycoprotein receptor are capable of being infected with HCV, and supporting culturing of the virus.

Title: A control architecture using an embedded signal status protocol
Inventor: LANDRY JOSEPH ELIDE
IPC: H04L69/40
Filed: 1998-09-23
Granted: 2001-09-04
Abstract: A network element with a centralized switch fabric is able to support multiple switching functions while meeting established performance requirements by using a control system based on an embedded signal status protocol. Generally, each input signal within a transmission path is monitored to derive signal status information, which is then individually encoded and embedded within the input signal. The embedded signal status can be decoded and provided as input to control logic forprocessing at any point within the transmission path, as necessary. In the case of a centralized switch fabric, the control logic resolves an address of a single input signal based on the embedded signal status and provides this resolved address to the switch fabric so that the appropriate input signal can be selected. In the present invention, the control logic may be configured to support any given application, e.g., "path-in-line" protection switching, whereby each configuration of control logic constitutes anapplication control set that supports the performance requirements of that givenapplication.

Abstract: Flow parameters in a fluid delivery assembly are determined by monitoring pressure responses and processing those responses along with information regarding the fluid flow.      In one aspect, a processor controls the pump to pump flow quantities in accordance with a pseudorandom code.      Portions of the resulting pressure signal sensed at the conduit is averaged, and the averaged values are then decoded in accordance with the pseudorandom code. An estimate of the equilibrium pressure is generated from the decoded average pressure values, while a summation of the pressure samples is generated from the undecoded pressure signals. The resistance to fluid flow of the system is determined from the estimated equilibrium pressure and pressure summation. For low flow rates, a processor controls the pump to pump fluid in a series of fluid boluses, with each fluid bolus delivered in the beginning of a separate timeslot. The equilibrium pressure is measured at the end of each timeslsot, and a summation of the pressure samples is generated from the pressure signals. For high flow rates, the pump is controlled to vary the flow rate and the change in pressure is divided by the change in flow to directly determine the resistance. A resistance display continuously displays the resistance of the system. The pseudorandom coding and decoding can be used to filter out pressure-response crosstalk caused by multiple fluid infusion segments feeding into a common line.
